As Ajax's trusted roofing experts, we understand the unique challenges our lakefront climate presents to Durham homeowners. From the harsh winter winds sweeping across the Ajax Waterfront to the summer humidity affecting homes in Pickering Village, your roof needs to stand up to diverse weather conditions while protecting your family.
As Owens Corning Platinum Preferred Contractors and GAF Certified installers, we bring premier roofing solutions to growing neighborhoods like Williamsburg and Rossland. Our in-house crews (never subcontractors) are specially trained to install high-performance Owens Corning roofing systems, including their Duration® series architectural shingles that withstand our challenging lakefront climate.
We provide comprehensive exterior contracting services to homeowners throughout Ajax and surrounding areas.

We've seen firsthand how Ajax's proximity to Lake Ontario affects roofing materials. That's why we recommend complete roofing systems with enhanced wind resistance for waterfront properties and proper ventilation solutions for inland homes dealing with temperature fluctuations. Our lifetime workmanship warranty, backed by our outstanding Google reviews, gives Ajax homeowners complete peace of mind.
Recently, we completed several full roof replacements in Pickering Village, where many heritage-style homes required special attention to architectural details while upgrading to modern materials. In the Rossland area, we've helped growing families protect their investments with durable GAF Timberline HDZ® shingles that offer superior protection against wind-driven rain.
